術中の血管損傷に起因した脳動脈瘤の1症例

Intracranial Aneurysm due to Arterial Injury during Surgery:Case Report

Ⅰ．緒言

　外傷性脳動脈瘤は，外傷と脳動脈瘤発生との因果関係を疑問視する意見もまぬがれず，報告例は稀である．

　最近，われわれは髄膜腫の摘出術をうけた症例に，術後の血管撮影ではじめて脳動脈瘤を認め，再開頭によってそれを確認する機会を得た．これは，術中の血管損傷による外傷性脳動脈瘤と考えられるので，ここに報告する．

This 38-year-old housewife had been operated on for intracranial and orbital meningioma four times, the last being on Oct. 30, 1975.
